Southeast Asian peoples are more commonly referred to as Oriental in Britain, however in the United States this is a pejorative term. Whereas in the US many people from the Indian subcontinent are labelled Hindus or Indians, again a term that would cause serious offence if used in the UK, especially if it was directed at a (Muslim) resident of Pakistan.

I suppose such are the complications of attempting to apply geographic terms to races of people, for human beings have the annoying habit of moving from place to place and refusing to be bound by artificial geographic boundaries.
